My invention relates to containers and more particularly to that type of containers having fibrous cylindrical bodies in laminated form and metal closures for the top and bottom.

The objects of my invention, among other things, are to provide an improved sealing joint for the open ends of the container when the metal closures or covers are applied and secured, more particularly to the top of the container, whereby the head cover may be ailixed firmly in place while providing a tight sealing joint around the,

container rim; also to pro-vide an improved seal Vor gasket construction that dispenses with the use of ay binding agent or adhesive, and at the same time reinforces the rim portion or margin of the open end of the laminated fibrous container, which is of advantage when the metal closure or cover is inserted in the open end and forced into sealing position on the slightly yielding fibrous body in the Zone of the gasket where eiective and uniform sealing is important.

A further object of my invention is toprovde a compressible gasket secured to the 'outer walls of the body slightly below the rim of the open end of the container, and so arranged that when the rim margin of the fibrous body is curved outwardly and over the gasket as the metal closure is applied to the container, the compression of the curved rim margin and gasket will aord a tight and uniform seal to prevent leakage of the contents of the container, and at the same time the compressed gasket affords a xed circular support so as to secure the metal cover or olo'- sure firmly in place within the rim of the container by having the cover clamping devices bear against the under side of the gasket.

Other advantages of my invention will be set forth in the following description taken in connection with the drawing.

2 Similar numerals refer to similar parts throughout the several iigures. j

Referring to Figs. 1-5, the cylindrical body Si of the container is preferably made of iibrousV material in laminated or multi-layer form with the lower edge of the bottom portion closed by the 'seam It! in any suitable manner. Around the Y outside of top portion of the body 9 slightly below .the rim edge il, the circular seal jor gasket I2, preferably made of compressible material such as twisted paperrope, is secured by the continu-V ous line stitching I3 passing through the body; Other types of securing means may be used, kbut I prefer the continuous line of stitching I 3 as Ishown in Fig. 5, which enables the gasket I2 to be slightly compressed without injuring or loos-` ening the stitching. This annular line of stit'chf ing I3, while holding the gasket` I2 firmly in placeA alsoY reinforces the margin of the body Aat lil where the rim edge I I is slightly flared outwardly as shown inFig. 2 for the insertion of the metal closure kor cover I5 which lits into the opene'nd l of the container body 9 as shown in Fig. 3.

The cover I5 shown in Figs. l-3 is the wellknown closure for containers of the lug type having the slotted lugs I5 arranged in spacedapart relation around the circumference of the cover l5. The cover I5 has the central countersunk panel Il which merges in the annular vertical wall I8 that fits snugly against the inner wall of the body 9 (Fig. 3) when the cover i5 is applied to the body. This annular wall i8 merges with the curved wall I9 from which the lugs I depend so as to form an inverted U-shaped channe1 2D adapted to rit over and enclose the rim of the body 9 and the gasket I2 (Figs. 2 and 3), when the cover I5 is forced downwardly into the body. The lugs Iii are then bent inwardly by the closing tool (not shown) with their end portions 2| bearing against the outer walls of the body t. The lugs I6 also press upwardly again-st the under side of the gasket i2, and the channel Qi: curves outwardly the flared rim edge I I from the position shown in Fig. 2 to that shown inFigs. 3 and 4 so as to form a tight seal on the open end of the body 9 as the cover 5 and lugs I6 curl outwardly and compress the rim edge II around the upper side of the gasket Ii; at the same time the lug ends 2l apply pressure beneath the` gasket I2 'which also acts to hold the lugs I6 in place. The

, stitching I3 reinforces the body margin Id below the rim edge II, and also serves as an annular hinge for the rim edge II when outwardly flared and also during the subsequent curling of such rim edge II over the gasket I2 as shown in Fig. 3.

The lug ends 2| also bear upwardly against the under side of the gasket I2 which affords a yielding abutment for the lug ends 2|.

In Figs. 6-8, I have shown a modified form of cover and attaching ring therefor. VIn this modied form the cover I5 has the central panel Il and vertical annular wall I8 with channel 22 that is semi-circular in cross-sectionA as shown in Fig.r8. The attaching ring 23 is of the usual construction that ts snugly over the cover channel 22, and has lits ends formed with transverselydisposed clips 24 and 25. The clips 24 and 25 have holes bored in alinement through which the threaded bolt 26 passes with the nut 21 screwed on the threaded bolt 26 as shown in Figs. 6 and 7. When the clips 24 and 25 are drawn toward each other by the bolt 26 and nut 21 in clamping the ring 23 to the cover I5, the eover channel 22 and ring 23 curl outwardly the rim edge I'I and squeeze this rim edge II and gasket I2 together to provide a tight seal, the gasket I 2 also serving to hold the ring 23 in proper horizontal alinement while securing the cover I5 in place.

Other types of cover closures may be used to effect the same advantageous result in securing an eiective seal by bending over the flared rim edge II and compressing same along with the gasket I2 to provide a tight and uniform sealing for the closure extending around the open end of the container. v Y

Various changes in the form, construction and disposition of thepartsmay be made without departing from the scope of my invention or sacrificing its advantages in use.

I claim as my invention:

1. In a container having a brous laminated body with an open end, va compressible gasket of twisted fibrous material fastened by stitching to the outer wall of the body slightly below and in mutual parallelism with the rim edge of said open end.

2. In a container having a fibrous laminated body with an open end, a compressible gasket of twisted paper rope fastened by a continuous line 4 of stitching passing through said gasket and outer wall of the body slightly below and in mutual parallelism with the rim edge of said open end.

3. A container comprising a fibrous laminated cylindrical body having an open end outwardly iiared around its margin, a metal closure having a counter-sunk center portion itted snugly within, and also having a rim portion overlapping, said open end, and an annular gasket of compressible material fastened permanently to the body by stitching passing through the entire wall thereof substantially along the base of the ared margin and mutually parallel with its rim edge and also adapted to be compressed in a plurality of directions by the closure rim between the body, flared margin and closure when the latter is forced into sealing position, said rim portion of the closure also curling and compressing said iiared margin over said gasket outwardly on the annular hinge formed by the stitching and also compressing the gasket inwardly and upwardly against the body and curled ared margin, Y

4. A container comprising a brous laminated cylindrical body having an open end outwardly dared around its margin, a metal closure having a counter-sunk center portion the sidewalls of which fit snugly within said open end with an outer curved wall rim portion overlapping the flared margin of the body, an annular gasket of fibrous material more compressible than the body fastened permanently to the body by stitching passing through the entire wall thereof substantially along the base of the flared margin, and means for positively locking the closure to the open end, thereby causing its outer rim portion to be bent inwardly to forcibly compress the gasv ket in a plurality of directions against the body and iiared margin and also to curl said iiared margin outwardly on the line of said stitching between the gasket and said outer rim portion while compressing same against the gasket when the closure is locked in sealing position.
